NAME
Geo::Coder::Yahoo - Geocode addresses with the Yahoo! API
SYNOPSIS
Provides a thin Perl interface to the Yahoo! Geocoding API.

my $geocoder = Geo::Coder::Yahoo->new(appid => 'my_app' );
my $location = $geocoder->geocode( location => 'Hollywood and Highland, Los Angeles, CA' );

PROXY SETTINGS
We use the standard proxy setting environment variables via LWP. See the
LWP documentation for more information.
METHODS
new
Geo::Coder::Yahoo->new(appid => $appid)
Geo::Coder::Yahoo->new(appid => $appid, on_error => sub { ... })
Instantiates a new object.
appid specifies your Yahoo Application ID. You can register at
.
If you don't specify it here you must specify it when calling geocode.
on_error specifies an error handler to be called if the HTTP response
code does not indicate success. The subroutine is called with the
geocode object as the first argument and the HTTP::Response object as
the second. The return value from the subroutine is used as the return
value from "geocode".
geocode( location => $location )
Parameters are the URI arguments documented on the Yahoo API page
(location, street, city, state, zip). You usually just need one of them
to get results.
"geocode" returns a reference to an array of results (an arrayref). More
than one result may be returned if the given address is ambiguous.
Each result in the arrayref is a hashref with data like the following
example:
{
'country' => 'US',
'longitude' => '-118.3387',
'state' => 'CA',
'zip' => '90028',
'city' => 'LOS ANGELES',
'latitude' => '34.1016',
'warning' => 'The exact location could not be found, here is the closest match: Hollywood Blvd At N Highland Ave, Los Angeles, CA 90028',
'address' => 'HOLLYWOOD BLVD AT N HIGHLAND AVE',
'precision' => 'address'
}
precision
The precision of the address used for geocoding, from specific
street address all the way up to country, depending on the precision
of the address that could be extracted. Possible values, from most
specific to most general are:
address
street
zip+4
zip+2
zip
city
state
country
warning
If the exact address was not found, the closest available match will
be noted here.
latitude
The latitude of the location.
longitude
The longitude of the location.
address
Street address of the result, if a specific location could be
determined.
city
City in which the result is located.
state
State in which the result is located.
zip Zip code, if known.
country
Country in which the result is located.
